Description

점농어와 민농어의 교잡에 의한 신품종 농어{IMPROVED SPECIES OF SEA BASS PRODUCED BY HYBRIDIZING SEA BASSES AND SPOTTED SEA BASSES}New species sea bass by hybridization between spot and sea bass {IMPROVED SPECIES OF SEA BASS PRODUCED BY HYBRIDIZING SEA BASSES AND SPOTTED SEA BASSES}

본 발명은 점농어와 민농어의 교잡에 의한 신품종 농어에 관한 것으로, 보다 상세히 말하면 산란기가 빠른 점농어와 산란기가 늦은 민농어의 성성숙을 인위적으로 조절하여 생식시기를 일치시키고 두 종을 교잡시켜서 생산하는 점농어와 민농어의 교잡에 의한 신품종 농어에 관한 것이다.The present invention relates to a new species sea bass by hybridization between spot and sea bass, more specifically, the spawning season of the sea bass fast spawning and late spawning period artificially controls the maturation of maturity to match the reproduction time and produced by hybridizing the two species It relates to a new breed sea bass by the hybridization of spot and sea bass.

자연상태에서 산란기가 10월∼11월인 점농어는 성장속도가 빠르다는 특성이 있는 반면 작은 크기의 점농어는 살이 무르기 때문에 상품 가치가 낮아 1㎏이상의 대형으로 키워야 한다. 민농어는 자연 산란기가 1월∼2월이며 맛이 좋아 횟감으로 인기가 있으며 또한 대형으로의 출하는 물론 소형의 경우에도 살이 단단하고 맛이 좋아 세꼬시(뼈꼬시)용으로 출하될 수 있는 장점이 있다. 그러나 점농어에 비해 성장이 느리다는 단점도 있다.In nature, the spotted sea bass, which are laid from October to November, is characterized by a rapid growth rate, while the smaller spotted sea bass must be grown to a large size of more than 1 kilogram because of their low weight. The sea bass has a natural spawning season from January to February, and it is popular as a sashimi for its good taste. It is also good for sashimi (seasoned fish). have. However, it also has the disadvantage of slow growth compared to spotted fish.

좋은 성장율을 지닌 점농어와 크기에 상관없이 맛이 좋은 민농어는 생식 시기가 서로 달라 자연 상태에서는 수정이 일어날 수 없었기 때문에 지금까지 민농어와 점농어의 교잡종 집단이 나타나지 않았으며 또한 사람에 의한 인위적인 교잡 시도도 없었다.Soybeans with good growth rate and tasteless sea bass, regardless of size, have not reproduced in nature because fertilization could not occur in the natural state. There was no hybridization attempt.

이에 본원은 빠른 성장율을 갖는 점농어와 맛이 뛰어난 민농어의 우수한 형질들을 이어받는 신품종 농어를 생산하고자 농어에 대해 지속적인 연구 실험을 거듭하여왔고, 그 결과 산란기가 서로 다른 두 어종의 성성숙을 인위적으로 조절하여 산란 시기를 일치시키고 두 어종을 교잡하여 교잡종을 생산하는 본 발명을 안출하게 되었다.In order to produce a new breed of sea bass, which inherits the excellent traits of fast-growing spotted sea bass and excellent tasting sea bass, we have continuously conducted experiments on sea bass. The present invention has been devised to control the spawning time and to hybridize two species to produce a hybrid.

즉, 본 발명은 농어의 사육환경을 수온은 9∼23℃로, 광주기는 최하치 0 에서부터 최고치 3,500lux로, 또 낮 길이를 7∼13시간의 범위 내에서 각기 상호 조절한 후, 성성숙 유도를 위해 민농어와 점농어의 암컷에 생식선 자극호르몬-방출호르몬 유사체(GnRH-analogue; Gonadotropin Releasing Hormone-analogue) 또는 황체자극흐르몬-방출호르몬 유사체(LHRH-analogue; Luteinizing Hormone Releasing Hormone-analogue)를 처리하고 수컷에 생식소 자극호르몬 유사체인 인간 태반성 생식선 자극호르몬(HCG; Human Chorionic Gonadotropin) 또는 어류의 뇌하수체 추출물을 처리하여 두 어종의 산란시기를 일치시켜 점농어 암컷과 민농어 수컷 또는 점농어 수컷과 민농어 암컷을 교잡함으로써 생산되는 것을 특징으로 한다.That is, in the present invention, the water temperature is 9-23 ° C. in the rearing environment of the perch, and the photoperiod is adjusted from 0 to the highest value of 3,500 lux, and the daytime length is controlled within the range of 7 to 13 hours, respectively, to induce sexual maturity. GnRH-analogue; Gonadotropin Releasing Hormone-analogue or LHRH-analogue; Luteinizing Hormone Releasing Hormone-analogue The males were treated with human placental gonadotropin (HCG) or pituitary gland extract of fish to match the spawning timing of the two fishes. It is characterized by being produced by hybridizing bass females.

농어는 환경의 변화에 민감한 어종으로서 양식용 탱크 또는 가두리에서는 산란 유도가 불가능하므로 친어의 성성숙을 유도하기 위하여 호르몬을 처리하는 동시에 상기와 같이 사육환경을 조절하여준다.Perch is a fish species sensitive to changes in the environment, so it is not possible to induce spawning in aquaculture tanks or cages, and in order to induce maturity of the parent fish, it controls the breeding environment as described above.

민농어의 경우 사육환경의 수온은 9∼17℃로, 광주기는 조도 최하치 0 에서부터 최고치 2,000lux의 범위 내에서 낮의 길이를 7∼13시간으로 조절하고, 점농어의 경우 사육환경의 수온은 14∼23℃로, 광주기는 조도 최하치 0 에서부터 최고치 3,500lux의 범위 내에서 낮의 길이를 8∼13시간으로 조절하는 것이 바람직하다.In the case of fish perch, the water temperature of the breeding environment is 9 ~ 17 ℃, and during the photoperiod, the daytime length is adjusted to 7 ~ 13 hours within the range of 0 to 2,000lux of maximum illuminance. At 14-23 degreeC, it is preferable to adjust a day length to 8 to 13 hours in the range of photoperiod in the range from the lowest illuminance 0 to the highest value 3,500 lux.

상기 점농어와 민농어의 암컷에 생식선 자극호르몬-방출호르몬 유사체 또는 황체자극호르몬-방출호르몬 유사체를 투여할 때 100∼1,600㎍/㎏의 농도범위로 투여하며 최적의 효과를 나타내는 농도는 400㎍/㎏이다.When administering the gonadotropin-releasing hormone analogue or luteinizing stimulating hormone-releasing hormone analogue to females of spot and minnow, the concentration range of 100-1,600 µg / kg and the optimum concentration is 400 µg / kg Kg.

상기 농어의 수컷에 처리하는 생식소 자극호르몬 유사체로서 인간 태반성 생식선 자극흐르몬을 투여할 때의 농도 범위는 200∼1,600IU/㎏이며 경제적인 면과 그 효과를 고려한 최적의 농도는 400IU/㎏이고, 어류의 뇌하수체 추출물을 사용할 경우에는 농도 0.1∼4p.e./㎏으로 처리하며 최적의 농도는 4p.e./㎏이다.When the human placental gonadotropin is administered as a gonad stimulating hormone analog to the male of the perch, the concentration range is 200-1,600 IU / kg, and the optimal concentration considering the economic aspect and its effect is 400 IU / kg. In case of using pituitary extract of fish, the concentration is 0.1 ~ 4p.e. / ㎏ and the optimal concentration is 4p.e./kg.

두 어종의 산란기가 일치하도록 민농어가 있는 탱크의 양식환경은 자연상태 보다 빠르게 변화하도록 조절하여 산란시키고자 하는 시기가 민농어의 산란기인 1 ∼2월의 환경이 되도록 만들어주고 점농어가 있는 탱크의 양식환경은 자연상태 보다 느리게 변화하도록 조절하여 산란시키고자 하는 시기가 점농어의 자연상태에서의 산란기인 10∼11월의 환경이 되도록 만든 후, 각 농어의 암컷과 수컷에 상기와 같이 호르몬을 각각 처리하여 민농어와 점농어의 인위적 성성숙을 유도한다. 즉, 민농어의 암컷과 수컷에는 산란기 초반에 점농어의 암컷과 수컷에는 산란기 후반에 호르몬을 처리하여 상기 점농어와 민농어로부터 채란 및 채정을 한다.The farming environment of the tank with the perch is adjusted to change faster than the natural state so that the spawning season of the two fish species matches, so that the time to spawn is the environment of the January-February, the season of the perch, and the tank with the spot perch The cultivation environment of the fish is controlled to change slowly than the natural state, so that the time of spawning is in the environment of October-November, which is the spawning season of the spot fish. Each treatment induces the artificial maturation of perch and spot perch. That is, females and males of the perch are treated with hormones in the early stages of spawning during the spawning season and females and males are spawned and harvested from the perch and the perch.

그 후, 건식법 및 습식법의 수정방법에 의하여 점농어 암컷과 민농어 수컷간의 교잡 및 점농어 수컷과 민농어 암컷간에 교잡을 시키며, 그에 대한 수정율, 부화율, 치어생산량 등을 조사한다.Thereafter, hybridization between spotted and perch males and hybridization between spotted and perch males is carried out by a modified method of dry and wet methods, and fertilization rate, hatching rate, and fry production are investigated.
